Models and Data

CDA Austerity Data Compendium
The data compendium on fiscal policy during the 2008-2012 global crisis brings together data from many sources, emphasizing European countries. The data cover topics including spending, debt, austerity, and interest rates for comparisons across countries. CDA analysts compiled the data compendium to allow other researchers to replicate and build on CDA’s work on the impact of spending and tax policy changes on economic growth.

Heritage Health Insurance and Microsimulation Model
The Heritage Health Insurance and Microsimulation model gives Heritage analysts the capability to conduct statistical studies of the effects of federal health policy on U.S. health insurance markets. This model can be utilized to analyze the effects of various changes in policy on the U.S. health care system. This includes estimating the costs of different policies as well as how a policy is likely to affect the number of people covered by insurance across market segments.

Heritage Foundation Individual Income Tax Model
The Heritage Foundation Individual Income Tax Model is used to simulate the likely changes in tax revenue and the distribution of tax burden as a result of changes in federal tax law. The model produces likely revenue cost estimates over a 10-year forecast period for scoring purposes. The data output of this model gives us the ability to quantify the likely impact of federal tax law changes on different demographic groups in the U.S.

Heritage Energy Model
The Heritage Energy Model (HEM) is a derivative of the National Energy Model System (NEMS). NEMS is used by the Energy Information Administration (EIA) of the U.S. Department of Energy as well as by various nongovernmental organizations for a variety of purposes, including forecasting the effects of energy policy changes on a wide range of leading economic indicators. The methodologies, assumptions, conclusions, and opinions in this report are entirely the work of statisticians and economists at The Heritage Foundation’s Center for Data Analysis (CDA) and have not been endorsed by and do not necessarily reflect the views of the developers of NEMS.
HEM is based on well-established economic theory as well as historical data and contains a series of modules that interact with each other for long-term forecasting. In particular, HEM focuses on the interactions among (1) the supply, conversion, and demand of energy in its various forms; (2) American energy and the overall American economy; (3) the American energy market and the world petroleum market; and (4) current production and consumption decisions as well as expectations about the future.
